What to do
Operators of AW109SP helicopters must inspect affected hydraulic pumps within specified flight hour limits and replace any discrepant parts before further flight. All affected parts must be replaced with serviceable parts by 1,600 flight hours since first installation or within 200 flight hours after the effective date, whichever is later. Installation of affected parts is prohibited after replacement or from the effective date for helicopters without affected parts.
Summary
EASA Airworthiness Directive 2019-0213 is an official regulatory document addressing hydraulic pumps installed on Leonardo S.p.A. AW109SP helicopters. It mandates inspection and replacement of specific hydraulic pumps with Part Number 109-0760-42-103, which are not eligible for installation, to ensure continued airworthiness and safety of the helicopters.
What changed
This new Airworthiness Directive introduces mandatory inspections of affected hydraulic pumps and requires their replacement with serviceable parts having Part Number 109-0760-42-105. It establishes compliance times based on flight hours and defines helicopter groups according to the number of affected parts installed.
Why it matters
This directive is critical for aviation professionals as it addresses a potential unsafe condition that could lead to hydraulic pump failure and loss of helicopter control. Operators and maintenance organizations must comply to maintain airworthiness and avoid operational disruptions or safety incidents.
